Wireless power supply system

The rise of the use of electronic devices on the go, is driving the need to find a better way of keeping those devices powered on. Wireless power transfer (WPT), is one solution being explored for this purpose. It has been applied in a variety of commercial applications spanning personal consumer electronic devices such as mobile phones to, safety conscious devices such as rechargeable electric toothbrushes, to the biomedical field, where power needs to be delivered to places without direct access. The majority of these devices utilise inductively coupled coils to achieve the power transfer. This paper presents the initial development of a magnetic resonance coupling system, aimed at improving power transfer efficiency, paramount to obtaining widespread acceptance of the technology. The design is simulated using COMSOL.
